The "sulfurized smoked finish" is a technique that expresses the dark brown color that copper alloys naturally develop over a long period of time using metals other than copper alloys. Rather than simply mimicking the color through painting, this finish incorporates the technique of "sulfurized smoked finish" to recreate its texture. Additionally, because it is handcrafted by our artisans, we can accommodate a variety of requests for colors ranging from light to dark, and we can also provide finishes for the metal surface such as hairline polishing and vibration polishing. 【Features】 ■ Expresses the dark brown color that copper alloys naturally develop over a long period of time using metals other than copper alloys. ■ Recreates the texture while incorporating the technique of "sulfurized smoked finish." ■ Handcrafted by our artisans. ■ Can accommodate a variety of requests for colors ranging from light to dark. ■ Finishes for the metal surface can include hairline polishing and vibration polishing. *For more details, please refer to the PDF document or feel free to contact us.
